production The UK’s highly sophisticated salt manufacturing plants have some far simpler roots. From the Roman times until the 1960s, salt was produced by boiling brine in shallow, open pans over huge wood or coal furnaces. Entire families would work the pans for very long hours - scooping salt crystals out of the boiling water as they formed. A great deal has changed since then and the UK is amongst the industry’s world leaders in terms of technology. Almost 100 countries across the world have facilities for producing white salt, ranging from primitive solar evaporation, to advanced, multi-stage evaporation in salt refineries. Read about how white salt is made. The method of producing rock salt has also changed significantly over the years from men hacking at the candle-lit salt-face with pick-axes, to a highly efficient, modern industry.
